Figure 4. Fraction of premature responses before (gray) and after (red) bilateral dACC ablation.

Figure 4

(A) False start fractions in six patients for the simple reaction time task (S1–S3) and the reward-dependent decision making task (S4–S6). (B) False start fractions in the three conditions of the reward-dependent decision making task, grouping across patients (S4–S6). Circles mark individual false start fractions for S4–S6. In both panels, asterisks indicate p<0.05, and error bars indicate 66% confidence intervals, analogous to standard error of the mean (standard error bars). For bars in panel A, proceeding from left to right, N = 90, 30, 120, 30, 84, 31, 533, 112, 816, 125, 805, 133. For bars in panel B, proceeding from left to right, N = 1676, 285, 239, 43, 239, 4.
